Скачать или смотреть How Does t-SNE Distort Global Data Structure?

Ever wondered about the hidden pitfalls of t-SNE when visualizing complex datasets? This video unpacks a critical aspect of t-SNE: its inherent tendency to distort the global structure of your data. We explore why, despite its power in revealing local relationships, t-SNE can often mislead you about the overall shape and distances between distinct clusters.

In this insightful discussion, we uncover:
► The fundamental trade-off between preserving local versus global data structures in dimensionality reduction techniques.
► Why t-SNE excels at showing cluster separation but struggles with accurately representing inter-cluster distances and relative positioning.
► Practical considerations for interpreting t-SNE plots and understanding their inherent limitations.
► Key factors that contribute to global distortions and how they can impact your data analysis.
